A high-level, rapid review (1) was conducted on oxygen therapy issues studied in the past 10 years in acute care settings. The main objective was to determine the appropriateness/inappropriateness of use, safety issues, and quality of care associated with oxygen prescription, administration, and monitoring. The results from this review were used to inform an upcoming provincial oxygen summit.

The Health Technology Assessment review (1) used a standardized rapid review approach: a comprehensive search of literature (published in English from 2005 to 2016), study selection using a priori developed criteria, and a qualitative synthesis of the results. Iterative interactions with the requester were necessary to clarify and refine the research questions, scope, and inclusion criteria.

Twenty-four audit studies were reviewed, the majority published after 2011, in the United Kingdom, and also in single institutions. Twelve studies reported effects after implementing interventions for improvement of oxygen prescription. Many studies had caveats on design, data reporting, and outcomes, or they lacked an explanation of the methods of analysis. Studies conducted in rural settings, and on infants and children were unavailable. The reported issues with oxygen therapy included: a lack or an inconsistency of compliance with guidelines, local policies, and standards; inappropriate prescription and administration; variability in practice among healthcare providers; and suboptimal monitoring, including poor standards of medical chart documentation for patients receiving oxygen therapy, such as incomplete details on flow rate and oxygen concentration.

Possibly due to the general tendency to publish research findings that have statistically significant results, relatively few publications were found in the literature search. The universal use of oxygen therapy and the enrolment of consecutive patients in some of the studies increase the applicability of the findings to other institutions. The rapid review provided a timely synthesis of the available, credible research for use by local stakeholders for further discussions and planning.
